ISTS802, ISTS802A, ISTS802B, ISTS802C 0.5mm APERTURE OPTO-ELECTRONIC SINGLE CHANNEL WIDE GAP SLOTTED INTERRUPTER SWITCHES WITH TRANSISTOR SENSORS DESCRIPTION 3.3 The ISTS802 series of opaque photointerrupters DIA are single channel switches consisting of a 1 Gallium Arsenide infrared emitting diode and a NPN silicon photo transistor mounted in a 2 polycarbonate housing. The package is designed to optimise the mechanical resolution, coupling efficiency, ambient light rejection, cost and 11.3 reliability. Operating on the principle that objects 10.9 opaque to infrared will interrupt the transmission of light between an infrared emitting diode and a photo sensor switching the output from an "ON" state to an "OFF" state.
